[0075] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0076] Figure 1 is a schematic diagram of a printing device according to an exemplary embodiment Figure 1 ; Figure 2 is a schematic diagram of the structure of a terminal device according to an exemplary embodiment; Figure 3 is a schematic diagram showing a structure in which a terminal device and a printing device are fixedly connected according to an exemplary embodiment; Figure 1-3 As shown, the printing device 100 includes: a housing 103 , a connection module (not shown in the figure), a communication module 104 , a printing module (not shown in the figure) and a film outlet 102 .

[0077] Housing 101;

[0078] A connection module, located on the housing 101, configured to detachably fix the terminal device 200 to the printing device 100; a communication module 104, configured to establish a communication connection between the printing device 100 and the terminal device 200;

[0079] A printing module, connected to the communication module 104, configured to execute a printing instruction transmitted by the communication module 104; wherein the printing instruction is generated by the terminal device 200 based on a printing event for a target image;

[0080] The film outlet 102 is formed on the housing 101 and is configured as an image entity for outputting the target image.

[0081] It is understandable that the material of the shell can be plastic or metal, and the embodiments of the present disclosure are not limited to this.

[0082] In some embodiments, when the shell of the printing device is made of plastic, the shell not only has the advantages of being drop-resistant and easy to manufacture, but also can provide users with a variety of color and style options.

[0083] Here, the shape of the shell can be a square body or a cylindrical body, and the present disclosure does not limit this.

[0084] It is understandable that the size of the shell changes with the size and number of the components inside the printing device. When the shapes of the components inside the printing device are larger and the number of the components is larger, the shell of the printing device is larger.

[0085] It should be explained that, in order to connect the printing device with the terminal device, a connection module needs to be provided on the housing of the printing device so that the terminal device can be detachably fixed to the printing device.

[0086] In some embodiments, the terminal device is a flat screen device. When the terminal device is fixed to the printing device, the entire housing of the flat screen device can be detachably fixed to the printing device.

[0087] In some other embodiments, the terminal device is a bifold folding screen device, and when the terminal device is changed from a closed state to a folded state, the first folding portion and the second folding portion of the terminal device can be placed in an up-and-down position relationship, or the first folding portion and the second folding portion can be placed in a left-and-right position relationship. Therefore, when the terminal device is fixed to the printing device, the first folding portion of the bifold folding screen device can be detachably fixed to the printing device.

[0088] Here, when the first folding portion of the terminal device is detachably fixed to the printing device, an angle is formed between the second folding portion and the first folding portion. The angle can be any angle between 0 degrees and 180 degrees, which is not limited in the embodiment of the present disclosure.

[0089] It can be understood that the detachable connection can be a pin connection, a bayonet connection or a nut connection, and the embodiments of the present disclosure are not limited to this.

[0090] Here, the latch connection utilizes the elastic deformation of the latch to achieve connection, has a simple structure and is easy to disassemble; the bayonet connection is achieved by socketing concave and convex structures on two or more parts, has a compact structure and a firm connection; the nut connection is achieved by connecting through a nut and is easy to disassemble.

[0091] It should be noted that in order to realize data transmission between the terminal device and the printing device, a communication module needs to be set in the printing device. After the terminal device and the communication module establish a communication connection, the terminal device and the printing device can transmit data information to each other to realize data exchange.

[0092] Here, the terminal device and the communication module may be connected by wire or by wireless, which is not limited in the embodiments of the present disclosure.

[0093] In some embodiments, when the terminal device and the communication module are connected by wire, a communication interface, such as a Universal Serial Bus (USB) interface, may be provided on the side wall of the housing of the terminal device, and the communication module may also be the USB interface. When data needs to be transmitted between the terminal device and the printing device, a double-headed data cable (i.e., a data cable with USB plugs at both ends) may be used to be inserted into the USB interface of the terminal device and the USB interface of the printing device, respectively.

[0094] It is understandable that in order to facilitate the wired connection between the terminal device and the communication module, the USB interface of the terminal device can be arranged on the side wall fixed to the printing device.

[0095] Here, the communication module serving as a USB interface may be disposed on the side wall of the housing, and may be away from the USB interface of the terminal device or may be close to the USB interface of the terminal device, and this is not limited in the present disclosure.

[0096] In other embodiments, when the terminal device and the communication module are wirelessly connected, a Bluetooth module or a WIFI module can be integrated in the terminal device, and a Bluetooth module or a WIFI module can also be integrated in the printing device, so that the printing device and the terminal device can establish a wireless connection, thereby enabling data transmission through both the WIFI module and the Bluetooth module.

[0097] It is understandable that after the printing module executes the printing instruction on the target image, in order to facilitate the user to obtain the physical image of the target image, a film outlet can be set on the shell of the printing device to output the image entity of the target image.

[0098] Here, the film outlet only needs to be able to output the printed photos, and the embodiment of the present disclosure does not limit the size of the film outlet.

[0099] Meanwhile, the film outlet may be arranged at any position of the housing of the printing device, and the embodiment of the present disclosure does not limit this.

[0100] Exemplarily, taking the printing device as an instant camera and the terminal device as a folding mobile phone as an example, the instant camera includes at least: a shell, a connection module, a communication module, a printing module and a film outlet; the folding mobile phone includes a first folding part and a second folding part.

[0101] Specifically, a shell is provided on the outer surface of the instant camera, and a connection module is provided on the shell, so that the first folding part of the foldable phone can be detachably fixed to the instant camera. When the first folding part is detachably fixed to the instant camera, an angle is formed between the second folding part of the foldable phone and the first folding part. At the same time, a communication module is provided in the instant camera to facilitate the establishment of a communication connection between the instant camera and the foldable phone; and a printing module connected to the communication module is provided to facilitate the execution of the printing instruction transmitted by the communication module, wherein the printing instruction is generated by the foldable phone based on a printing event for a target image; finally, a film outlet is provided on the shell to facilitate the output of the image entity of the target image.

[0102] In the disclosed embodiment, the printing device includes a shell, a connection module, a communication module, a printing module and a film outlet. By setting the connection module on the shell, the terminal device is detachably fixed to the printing device; then the communication module is used to realize the communication connection between the printing device and the terminal device; and the printing module is connected to the communication module so that the printing module executes the printing instruction transmitted by the communication module; wherein the printing instruction is generated by the terminal device based on a printing event for a target image; finally, a film outlet is formed on the shell to output a picture entity of the target image.

[0103] In this way, after establishing a communication connection between the printing device and the terminal device, the terminal device can send the target image to the printing device, and the printing device prints the target image, so that the user can obtain the physical image corresponding to the target image in real time, which is conducive to improving the user's operating experience.

[0104] In some embodiments, Figure 4 is a schematic diagram of a printing device according to an exemplary embodiment Figure 2 ;like Figure 4 As shown, the connection module includes:

[0105] The accommodating portion 103 has an accommodating space whose size matches that of the first folding portion 201 of the terminal device 200 and is configured to snap-fit ​​the first folding portion 201; and / or

[0106] The magnetic attraction portion 107 is configured to attract the first folding portion 201 .

[0107] It should be noted that, in order to fixedly connect the first folding portion of the terminal device with the printing device, the connection module may include a receiving portion and / or a magnetic attraction portion.

[0108] It is understandable that when the first folding portion of the terminal device can be completely accommodated in the accommodating portion, the fixing effect between the first folding portion and the accommodating portion is better. Therefore, in the embodiment of the present disclosure, the accommodating space of the accommodating portion is set to a size that matches the size of the first folding portion of the terminal device, so that the accommodating portion is clamped with the first folding portion.

[0109] It should be explained that the clamping is to fix two objects together by the binding force between the two objects, and usually requires a large force to disassemble. In order to improve the clamping force between the terminal device and the printing device, a structure such as a latch or a protrusion can be set between the terminal device and the printing device, so that the terminal device and the printing device are fixedly connected together, thereby having a strong holding force.

[0110] In some embodiments, a limiting protrusion may be provided on the side wall of the accommodating portion, and a limiting groove may be provided on the side wall of the first folding portion. When the first folding portion of the terminal device is connected to the printing device, the limiting protrusion on the side wall of the accommodating portion is engaged with the limiting groove on the side wall of the first folding portion, thereby fixing the first folding portion to the printing device.

[0111] It is understandable that when the connecting module includes a magnetic attraction portion, when the first folding portion approaches the shell of the printing device, the magnetic attraction portion on the shell can absorb the first folding portion, so that the printing device is fixedly connected to the first folding portion.

[0112] It should be noted that magnetic attraction is a process that uses the interaction between a magnetic field and a magnetic material to achieve the adsorption and fixation of an object. In the embodiment of the present disclosure, a magnetic material is provided inside the first folding portion. When the first folding portion is close to the magnetic attraction portion, a magnetic attraction will be generated between the first folding portion and the magnetic attraction portion, so that the terminal device and the printing device are tightly connected together. At the same time, this adsorption force can maintain the stability between the terminal device and the printing device, and can prevent the first folding portion of the terminal device from accidentally falling off or moving.

[0113] Here, the size and position of the magnetic attraction portion can be set arbitrarily, as long as the first folding portion can be fixed on the printing device, and the embodiment of the present disclosure does not limit this.

[0114] It is understandable that in order to improve the fixing effect between the first folding part and the printing device, the connecting module may include a receiving part and a magnetic part, so that the first folding part can not only be fixed by snapping with the receiving part, but also can be fixed by adsorption with the magnetic part.

[0115] In the embodiment of the present disclosure, the connection module includes a receiving portion and / or a magnetic attraction portion, wherein the size of the receiving space of the receiving portion matches the size of the first folding portion of the terminal device, and can be snapped into the first folding portion; the magnetic attraction portion can adsorb the first folding portion. In this way, the present disclosure fixes the first folding portion of the terminal device to the printing device by setting the receiving portion and / or the magnetic attraction portion on the housing, which is convenient for users to carry and improves the user's operating experience.

[0116] In some embodiments, the accommodation portion 103 is an accommodation groove formed by the shell 101 being recessed inwardly.

[0117] It can be understood that, in order to better accommodate the first folding portion in the accommodating portion, the accommodating portion can be configured as an accommodating groove formed by the shell being recessed inwardly.

[0118] Here, the depth of the accommodating groove may be less than or equal to the thickness of the first folding portion, which is not limited in the embodiment of the present disclosure.

[0119] In some embodiments, in order to facilitate the removal of the first folded portion from the groove, the depth of the accommodating groove can be set to be smaller than the thickness of the first folded portion. When the first folded portion is placed in the accommodating groove, the accommodating groove only wraps a part of the structure of the first folded portion, so that the structure of the first folded portion not wrapped by the accommodating groove is exposed, thereby simplifying the removal process of the first folded portion.

[0120] For example, Figure 5a is a side view of a closed structure of a terminal device according to an exemplary embodiment; Figure 5b is a side view of a structure in which a terminal device and a printing device are fixedly connected according to an exemplary embodiment Figure 1 ; Figure 6a is a front view of a closed structure of a terminal device according to an exemplary embodiment; Figure 6b is a front view of a structure in which a terminal device and a printing device are fixedly connected according to an exemplary embodiment; Figure 7a is a top view of a closed structure of a terminal device according to an exemplary embodiment; Figure 7b is a top view of a structure in which a terminal device and a printing device are fixedly connected according to an exemplary embodiment; Figure 8ais a structural side view of a terminal device unfolded according to an exemplary embodiment; Figure 8b is a side view of a structure in which a terminal device and a printing device are fixedly connected according to an exemplary embodiment Figure 2 ;like Figure 5a-Figure 8b As shown, when the terminal device 200 and the printing device 100 need to be fixed, the first folding portion 201 of the terminal device 200 can be placed in the accommodating portion 103 of the printing device 100, thereby achieving a fixed connection between the printing device 100 and the terminal device 200.

[0121] In the disclosed embodiment, the accommodating portion is an accommodating groove formed by the inward depression of the shell, so that the accommodating groove completely accommodates the first folding portion of the terminal device, which is beneficial to improving the effect of the fixed connection between the first folding portion of the terminal device and the printing device.

[0122] In some embodiments, Figure 1 and Figure 4 As shown, the communication module 104 is located on the inner wall of the accommodating portion 103 , extends toward the accommodating space of the accommodating portion 103 , and is configured to be inserted into the communication interface on the first folding portion 201 when the first folding portion 201 is detachably fixed to the printing device 100 .

[0123] It should be noted that, in order to simplify the communication connection process between the printing device and the terminal device, a communication module can be provided on the inner side wall of the accommodating portion, wherein the communication module extends toward the accommodating space of the accommodating portion to form a USB connector. When the first folding portion is detachably fixed to the printing device, the communication module can be inserted into the communication interface on the first folding portion.

[0124] It is understandable that USB connectors are commonly used for data transmission between mobile phones, USB flash drives, etc. and computers. Using USB connectors to transmit data is currently the most commonly used data transmission method. Usually, a USB connector includes a plug body and a USB interface connected to the plug body. The USB interface is generally a square interface. When connecting, the USB male interface needs to correspond to the female interface, and the corresponding relationship between the two is unique.

[0125] In the disclosed embodiment, the communication module is a USB male interface formed on the inner side wall of the accommodating portion, and the communication interface on the first folding portion is a USB female interface. Therefore, when the first folding portion is detachably fixed to the printing device, the USB male interface corresponds to the USB female interface, thereby realizing the communication connection process between the printing device and the terminal device.

[0126] In some embodiments, in order to increase the insertion probability of the USB male head and the USB female head and reduce the rigid damage of the USB male head and the USB female head, a ring-shaped USB interface can be set, which makes the USB male head interface plugged in with the corresponding female head interface smoother, and can rotate 360 ​​degrees after insertion. At the same time, it prevents the USB male head interface from being twisted due to external force, thereby preventing the USB male head interface from being deformed or damaged, thereby increasing the service life of the USB male head interface and facilitating the plugging of the USB interface.

[0127] In the embodiment of the present disclosure, the communication module is arranged on the inner side wall of the accommodating portion, extending toward the accommodating space of the accommodating portion, and when the first folding portion is detachably fixed to the printing device, the communication module is inserted into the communication interface on the first folding portion. In this way, when the first folding portion of the terminal device is fixed to the printing device, the communication module of the printing device can be inserted into the communication interface of the terminal device, so that the printing device and the terminal device can establish a communication connection without a data cable, which is conducive to improving the user's operating experience.

[0128] In some embodiments, Figure 1 and Figure 4 As shown, the printing device 100 further includes:

[0129] At least one alignment portion 105 is formed at the bottom of the accommodating portion 103, opposite to the communication module 104, and configured to move to a bending space formed by bending between the first folding portion 201 and the second folding portion 202 of the terminal device 200 when the communication module 104 is successfully inserted into the communication interface;

[0130] The first folding portion 201 has a side with a display screen facing the second folding portion 202 has a side with a display screen.

[0131] It should be explained that if the communication module is not fully inserted into the communication interface of the terminal device, the communication connection between the printing device and the terminal device is unstable. In order to improve the reliability of the communication connection between the communication module and the terminal device, at least one alignment portion can be provided at the bottom of the accommodating portion, at a position opposite to the communication module. When the alignment portion fills the bending space formed by the bending between the first folding portion and the second folding portion, the communication module is successfully inserted into the communication interface, so that the printing device and the terminal device establish a reliable communication connection.

[0132] Therefore, in the embodiment of the present disclosure, the alignment portion is provided so that during the process of fixing the first folding portion and the accommodating portion, when the alignment portion fills the bending space formed by the bending between the first folding portion and the second folding portion, the user can feel the pressing effect of the alignment portion and know that the communication module has been successfully inserted into the communication interface.

[0133] In some embodiments, the alignment part can be an elastic material. When the alignment part moves to the gap formed between the first folding part, the first folding part and the second folding part, and the bottom of the accommodating part, on the one hand, due to the elastic material, it is not easy to damage the terminal device. On the other hand, due to the elastic effect of the alignment part on the first folding part, the communication module can be accurately inserted into the communication interface. Here, the number of alignment parts can be set arbitrarily, and the embodiments of the present disclosure are not limited to this.

[0134] At the same time, the thickness of the alignment portion can also be set arbitrarily, as long as it can fill the gap formed between the first folding portion and the second folding portion and between the bottoms of the accommodating portion, and the embodiment of the present disclosure is not limited to this.

[0135] In the embodiment of the present disclosure, the printing device further includes at least one alignment portion, which is formed at the bottom of the accommodating portion and is opposite to the communication module. When the communication module is successfully inserted into the communication interface, the alignment portion moves the bending space formed by the bending between the first folding portion and the second folding portion. In this way, the present disclosure provides an alignment portion, and during the process of inserting the communication module into the communication interface, based on the elastic effect of the alignment portion, the communication module is ensured to be accurately inserted into the communication interface, thereby improving the reliability of the communication connection between the printing device and the terminal device.

[0136] In some embodiments, the printing device 100 further includes:

[0137] At least one limiting portion is formed on the inner side wall of the accommodating portion 103 and is configured to abut against the first folding portion 201 located in the accommodating portion 103 .

[0138] It is understandable that after the first folding portion is fixed to the accommodating portion, when the user adjusts the angle between the first folding portion and the second folding portion, it is necessary to set a limiting portion to abut against the first folding portion located in the accommodating portion.

[0139] Therefore, in the embodiment of the present disclosure, by providing at least one limiting portion on the inner side wall of the accommodating portion, when the user adjusts the angle between the first folding portion and the second folding portion, the limiting portion can abut against the first folding portion located in the accommodating portion, thereby ensuring that the terminal device is in a hovering state.

[0140] It is understandable that the limiting portion may be an elastic member, and after the first folding portion is fixed to the accommodating portion, due to the elastic effect of the limiting portion, it can abut against the first folding portion in the accommodating portion, thereby ensuring the hovering state of the terminal device.

[0141] Here, the number of the limiting parts can be set arbitrarily, and the embodiments of the present disclosure are not limited to this.

[0142] In the disclosed embodiment, the printing device further comprises at least one limiting portion formed on the inner side wall of the accommodating portion, which can abut against the first folding portion located in the accommodating portion. In this way, after the first folding portion of the terminal device is fixed to the printing device, when the user adjusts the angle between the first folding portion and the second folding portion, the abutting effect of the limiting portion on the first folding portion is conducive to supporting the first folding portion, and is conducive to strengthening the fixed connection between the first folding portion and the printing device, thereby ensuring the hovering state of the terminal device.

[0143] In some embodiments, Figure 4 As shown, the magnetic attraction portion 107 is located at the bottom of the accommodating portion 103 , and is configured to provide an adsorption force to a side of the first folding portion 201 that contacts the bottom of the accommodating portion 103 when the first folding portion 201 is snapped onto the accommodating portion 103 .

[0144] It should be noted that, in order to strengthen the fixed connection between the terminal device and the printing device, the magnetic attraction portion can be provided at the bottom of the accommodating portion. When the first folding portion is snapped onto the accommodating portion, the magnetic attraction portion can provide an adsorption force to the side of the first folding portion that is in contact with the bottom of the accommodating portion, thereby ensuring that the first folding portion is snapped onto and fixed to the accommodating portion and can also be adsorbed and fixed to the magnetic attraction portion, thereby improving the fixing effect between the printing device and the first folding portion.

[0145] Here, the size of the magnetic attraction portion can be set arbitrarily, and the embodiment of the present disclosure does not limit this.

[0146] In the embodiment of the present disclosure, the magnetic attraction portion is located at the bottom of the accommodating portion, and when the first folding portion is snapped onto the accommodating portion, the magnetic attraction portion can provide an adsorption force to the side of the first folding portion that is in contact with the bottom of the accommodating portion. In this way, the present disclosure adds an adsorption fixation of the magnetic attraction portion on the basis of the snap-fit ​​fixation of the terminal device and the accommodating portion, thereby strengthening the fixed connection between the terminal device and the printing device and improving the user's operating experience.

[0147] In some embodiments, Figure 4 As shown, the printing device 100 further includes:

[0148] The movable part 106 is connected to the communication module 104 and is configured to send an adjustment instruction to the terminal device 200 through the communication module 104 based on the detection of an activity event; wherein the adjustment instruction indicates adjusting the shooting parameters of the terminal device 200.

[0149] It should be explained that in order to improve the user's ability to accurately adjust the shooting parameters of the terminal device, an active part can be set in the printing device. The active part is connected to the communication module. When an activity event is detected, an adjustment instruction is sent to the terminal device through the communication module to adjust the shooting parameters of the terminal device.

[0150] Here, the position of the movable part can be set arbitrarily as long as it is connected to the communication module, and the embodiment of the present disclosure does not limit this.

[0151] At the same time, the shape and size of the movable part can also be set arbitrarily according to needs, and the embodiments of the present disclosure are not limited to this.

[0152] In some embodiments, in order to improve the user's operating experience, the movable part can be set as a raised physical knob. When the printing device establishes a communication connection with the terminal device, by rotating the knob, the user has a real touch feeling, thereby accurately adjusting the shooting parameters of the terminal device.

[0153] In the embodiment of the present disclosure, the printing device further comprises a movable part connected to the communication module, and based on the detection of an activity event, an adjustment instruction is sent to the terminal device through the communication module; wherein the adjustment instruction indicates to adjust the shooting parameters of the terminal device. In this way, when the communication module sends the adjustment instruction to the terminal device, the present disclosure adjusts the shooting parameters of the terminal device through the movable part, so that the user has a real touch feeling, which is conducive to improving the precise control of the shooting parameters.

[0154] In some embodiments, the printing device 100 further includes:

[0155] The image acquisition module is configured to perform image acquisition based on the received image acquisition instruction.

[0156] It should be explained that, in order to further enhance the user's operating experience, the printing device is also provided with an image acquisition module, so that the user can directly use the printing device to acquire images and print the acquired images.

[0157] It can be understood that the working principle of the image acquisition module is that the light gathered by the object through the lens (lens) is converted into an electrical signal through the image sensor, which is then converted into a digital image signal through the internal image processor (ISP) and output to the digital signal processor (DSP) for processing, and then converted into an image signal in standard GRB, YUV and other formats.

[0158] Here, the type of the image acquisition module may be a CCD type or a CMOS type, which is not limited in the embodiments of the present disclosure.

[0159] In an embodiment of the present disclosure, the printing device also includes an image acquisition module, which can perform image acquisition based on the received image acquisition instructions. In this way, the printing device described in the present disclosure has the function of image acquisition, can directly acquire images, and then print the images as physical photos, which is conducive to improving the user's operating experience.

[0160] Fig. 9 A process diagram of a printing method according to an exemplary embodiment is shown. Figure 1 ;like Fig. 9 As shown, applied to the above-mentioned printing device, the printing method mainly includes the following steps:

[0161] In step 301, based on the communication connection with the terminal device, a print instruction sent by the terminal device is received; wherein the print instruction is generated by the terminal device based on a print event for a target image;

[0162] In step 302, the printing instruction is executed, and the image entity of the target image is output.

[0163] It needs to be explained that in order to allow users to obtain physical photos in real time, after the printing device establishes a communication connection with the terminal device, the terminal device can send a printing instruction to the printing device, so that the printing device executes the printing instruction to obtain the image entity corresponding to the target image.

[0164] It is understandable that after receiving the printing instruction, the printing device can execute the printing instruction using the printing module in the printing device, so that the user can obtain the image entity corresponding to the target image in real time, thereby improving the user's operating experience.

[0165] Here, the communication connection between the printing device and the terminal device may be a wired connection or a wireless connection, which is not limited in the embodiments of the present disclosure.

[0166] In some embodiments, after the communication module of the printing device is inserted into the communication interface of the terminal device, the printing device and the terminal device can further establish a wireless connection. In order to improve the security and reliability of transmission, both parties need to perform a communication check before the two devices establish a wireless connection. Specifically: first verify whether the other party is a device supported by the self-supported party. After the two parties make an initial connection, they will first communicate, send each other's project number to each other, and determine whether the name sent by the other party is in the self-support list. After confirming that the two parties are mutually supported devices, the two parties will establish a wireless connection channel.

[0167] Therefore, in the embodiment of the present disclosure, when the communication module of the printing device is disconnected from the communication interface of the terminal device, within a limited distance (that is, when the printing device and the terminal device are still wirelessly connected), the printing device can still receive the printing instructions sent by the terminal device, execute the printing instructions, and output the image entity of the target image.

[0168] Exemplarily, the printing device is a Polaroid camera. When the user presses the shutter button, the optical fiber enters the camera and is reflected and refracted by the optical components, and finally reaches the photosensitive element. The photosensitive element converts the optical fiber into an electrical signal, which is then transmitted to the circuit board of the Polaroid camera for processing. Finally, the circuit board sends the image to the printing module of the Polaroid camera, and the printing module prints the image on photographic paper through chemical treatment and thermal technology.

[0169] When using a Polaroid camera to take photos, some problems are likely to occur, such as insufficient light or long exposure time, which can easily result in poor photo quality; incorrect exposure time or improper exposure time compensation setting can easily result in the photo being too bright or too dark; and unclear photos when the handheld camera is unstable or the focus is inaccurate.

[0170] In addition, the Polaroid camera is an instant imaging camera that can quickly print the captured images on photo paper. Therefore, when the user uses the Polaroid camera, it is not convenient to select the captured images, and photos with poor imaging effects may also be printed, which is not conducive to improving the user's operating experience.

[0171] In the disclosed embodiment, the user does not need to use the printing device to capture images. The printing device can receive the target image sent by the terminal device and print the target image. Therefore, after the user sends the target image piece in the terminal device to the printing device in real time, the user can quickly obtain the physical photo. On the one hand, it is convenient for the user to record the travel moments and improve the user's operating experience; on the other hand, it can avoid the waste of printed paper in the printing device.

[0172] In the embodiment of the present disclosure, the printing device receives a printing instruction sent by the terminal device based on the communication connection between the printing device and the terminal device; wherein the printing instruction is generated by the terminal device based on a printing event for a target image; the printing instruction is executed, and the image entity of the target image is output. In this way, after the printing device establishes a communication connection with the terminal device, the terminal device can send the target image to the printing device, and the printing device prints the target image, so that the user can obtain the entity image corresponding to the target image in real time, which is conducive to improving the user's operation experience.

[0173] In some embodiments, the method further comprises:

[0174] The printing parameters are sent to the terminal device so that the terminal device displays the printing parameters through a display screen.

[0175] It is understandable that when a user needs to obtain physical photos corresponding to multiple target images, prompting the user in advance of the number of remaining printing papers is conducive to improving the user's operating experience. In the embodiment of the present disclosure, after the printing device and the terminal device are connected in communication, the printing device sends the printing parameters to the terminal device, so that the terminal device displays the printing parameters on the display screen.

[0176] Here, the printing parameters may be displayed on a display screen of a first folding portion of the terminal device, or may be displayed on a display screen of a second folding portion of the terminal device, and this embodiment of the present disclosure does not limit this.

[0177] In the disclosed embodiment, the printing device can send printing parameters to the terminal device so that the terminal device displays the printing parameters through a display screen, thereby facilitating the user to understand the number of remaining printing papers of the printing device, which is beneficial to improving the user's operating experience.

[0178] In some embodiments, the method further comprises:

[0179] In a case where the terminal device is in a preview mode, detecting an activity event based on the activity element;

[0180] An adjustment instruction corresponding to the activity event is generated, and the adjustment instruction is sent to the terminal device; wherein the adjustment instruction indicates adjusting a shooting parameter of the terminal device.

[0181] It should be noted that, although the display screen of the first folding portion has a control interface for adjusting the shooting parameters of the terminal device, the control interface is not conducive to the user's accurate control of the shooting parameters. Therefore, the embodiment of the present disclosure provides a movable part on the printing device so that the user has a real sense of touch, thereby ensuring that the user can accurately adjust the shooting parameters of the terminal device.

[0182] It can be understood that the active part is used to adjust the shooting parameters of the terminal device. Therefore, when the terminal device is in the preview mode, the printing device will generate an adjustment instruction corresponding to the activity event after the active part detects the activity event.

[0183] In some embodiments, if the movable part is a physical knob, the user can rotate the physical knob as needed to accurately adjust the shooting parameters of the terminal device so as to obtain an image that better meets the user's intention.

[0184] In the embodiment of the present disclosure, when the terminal device is in preview mode, an activity event is detected based on the movable part; the printing device generates an adjustment instruction corresponding to the activity event and sends the adjustment instruction to the terminal device; wherein the adjustment instruction indicates to adjust the shooting parameters of the terminal device. In this way, when the communication module sends the adjustment instruction to the terminal device, the present disclosure adjusts the shooting parameters of the terminal device through the movable part, so that the user has a real touch feeling, which is conducive to improving the precise control of the shooting parameters.

[0185] Fig.10 A process diagram of a printing method according to an exemplary embodiment is shown. Figure 2 ,like Fig.10 As shown, it is applied to a terminal device, and the terminal device can be detachably fixed to a printing device; the printing method mainly includes the following steps:

[0186] In step 401, when a printing event for a target image is detected, a printing instruction is generated;

[0187] In step 402, the printing instruction is sent to the printing device based on the communication connection with the printing device; wherein the printing instruction is used to instruct the printing device to output the image entity of the target image.

[0188] It should be noted that the rise of terminal devices has enabled the enlargement of device screens, making the devices not only easy to carry but also usable as large-screen devices.

[0189] In some embodiments, the terminal device may be a folding screen mobile phone with double screens, which can realize single-screen display and dual-screen display on a single machine, and support cross-screen roaming of images. After the dual screens of the mobile phone are opened from the folded state, they can be placed as upper and lower screens or left and right screens. When placed as upper and lower screens, the upper screen can be used as the main screen and the lower screen can be used as the keyboard.

[0190] However, in the related art, the accessories of the terminal device are relatively simple and do not expand the actual usage scenarios of users. In order to improve the user's operating experience of the terminal device, a new accessory can be set for the terminal device, and the accessory can print the image in the terminal device, so that the user can obtain the physical photo in real time.

[0191] Based on this, an embodiment of the present disclosure provides a printing method, which enables a terminal device to generate a printing instruction for a printing event of a target image. After the terminal device establishes a communication connection with the printing device, the terminal device sends the printing instruction to the printing device.

[0192] It is understandable that after receiving the printing instruction, the printing device can execute the printing instruction using the printing module in the printing device, so that the user can obtain the image entity corresponding to the target image.

[0193] In the embodiment of the present disclosure, when a printing event for a target image is detected, a printing instruction is generated; the terminal device sends the printing instruction to the printing device based on the communication connection between the terminal device and the printing device; wherein the printing instruction is used to instruct the printing device to output the image entity of the target image. In this way, after the printing device and the terminal device establish a communication connection, the terminal device can send the target image to the printing device, and the printing device prints the target image, so that the user can obtain the entity image in real time, which is conducive to improving the user's operation experience.

[0194] In some embodiments, the method further comprises:

[0195] When a selection event for the initial image is detected, watermark information is obtained;

[0196] The target image is generated based on the initial image and the watermark information.

[0197] It is understandable that in order to improve the user's operating experience and avoid wasting printing paper, before generating a print instruction for the target image, the user is required to select the target image from multiple initial images.

[0198] In some embodiments, the user can select an image with good imaging effect, so as to obtain a clearer entity picture.

[0199] It should be explained that, when a selection event for an initial image is detected, watermark information can be obtained. The user can choose whether to add the watermark information to the selected initial image, thereby further generating a target image.

[0200] In some embodiments, if the user chooses to add watermark information to the initial image, the target image to be printed is the initial image with the watermark information.

[0201] In other embodiments, if the user chooses not to add the watermark information to the initial image, the target image to be printed is the initial image without the watermark information.

[0202] Here, the watermark information may be a watermark automatically generated by the terminal device system, which is not limited in the embodiments of the present disclosure.

[0203] For example, the watermark information may be a Leica watermark. The Leica watermark simulates the shooting style and iconic watermark used by the famous German camera brand Leica. By adding words and logos such as "LEICA" and "Summilux" to the photographed photos, the photos appear more professional and advanced.

[0204] Here, the Leica watermark information includes but is not limited to the mobile phone model, photo taking time, photo taking parameters, longitude and latitude, etc.

[0205] In some embodiments, the user can adjust the text in the watermark information and the overall effect of the watermark information, including the font, size, relative position, whether to hide, overall size of the watermark information and transparency of the watermark information.

[0206] In the disclosed embodiment, when a selection event for an initial image is detected, watermark information is obtained; based on the initial image and the watermark information, the target image is generated, so that the user can pre-process the initial image, such as whether to add watermark information to the initial image, thereby helping to improve the user experience.

[0207] In some embodiments, the method further comprises:

[0208] When a shooting instruction is detected, the terminal device enters a preview mode and displays a preview interface through the display screen of the second folding portion;

[0209] In the preview mode, if a shooting operation on the display screen of the first folding portion is detected, the initial image is acquired.

[0210] It needs to be explained that the terminal device has a first folding part and a second folding part. When a shooting instruction is detected, the display screen of the second folding part can display a preview interface, and the display screen of the first folding part has a capture interface for controlling the preview interface.

[0211] It is understandable that in the preview mode, the user can capture the preview interface of the second folding part by touching the display screen of the first folding part. Specifically, the display screen of the second folding part displays the preview screen in real time, and when the user needs to capture the preview interface, the user captures the preview screen by touching the display screen of the first folding part.

[0212] In some embodiments, if the printing device is a Polaroid camera and the terminal device is a foldable mobile phone, after the Polaroid camera and the foldable mobile phone are connected, the image acquisition filter of the foldable mobile phone can be changed to the filter of the Polaroid camera. When a shooting instruction is detected, the filter effect displayed on the display screen of the second foldable part of the foldable mobile phone is consistent with the filter effect displayed on the image captured by the Polaroid camera.

[0213] In the embodiment of the present disclosure, when a shooting instruction is detected, the terminal device enters a preview mode and displays a preview interface through the display screen of the second folding part; in the preview mode, if a shooting operation on the display screen of the first folding part is detected, the initial image is captured, so that the user can use the first folding part to control the capture of the preview image of the display screen of the second folding part, which is beneficial to improving the convenience of user operation.

[0214] In some embodiments, the method further comprises:

[0215] In the preview mode, receiving an adjustment instruction sent by the printing device;

[0216] Adjusting the shooting parameters of the terminal device based on the adjustment instruction;

[0217] Wherein, the shooting parameters include: the distance from the optical center of the lens of the terminal device to the imaging plane.

[0218] It should be noted that, although the display screen of the first folding portion has a control interface for adjusting the shooting parameters of the terminal device, the control interface is not conducive to the user's accurate control of the shooting parameters. Therefore, the embodiment of the present disclosure provides a movable part on the printing device so that the user has a real sense of touch, thereby ensuring that the user can accurately adjust the shooting parameters of the terminal device.

[0219] It is understandable that when the display screen of the second folding part displays the preview image, the user can use the printing device to send an adjustment instruction to the terminal device according to his / her own needs. When the terminal device receives the adjustment instruction, it can adjust the shooting parameters of the terminal device.

[0220] Here, the shooting parameters may include the distance from the optical center of the lens of the terminal device to the imaging plane, that is, the focal length of the lens of the terminal device.

[0221] In some embodiments, if the movable part is a physical knob, the user can rotate the physical knob as needed to increase or decrease the focal length, so as to obtain an image that better meets the user's intention.

[0222] In the embodiment of the present disclosure, in the preview mode, an adjustment instruction sent by the printing device is received; and the shooting parameters of the terminal device are adjusted based on the adjustment instruction; wherein the shooting parameters include: the distance from the optical center of the lens of the terminal device to the imaging plane. In this way, when the communication module sends an adjustment instruction to the terminal device, the present disclosure adjusts the shooting parameters of the terminal device through the movable part, so that the user has a real touch feeling, which is conducive to improving the precise control of the shooting parameters.
